PROCESS OF UTILIZING LIQUEFIED GASES.

SPECIFICATION formingpart of Letters Patent No. 660,755, dated October 30, 1900.

Application filed November 4, 1899, serial No. 735,761. (No specimens.) 7

To all whom, it may concern:

Be it known that I, ARNOLD KREUSLER, a citizen of the United States, residing at New York, (Kreischerville,) borough ofRichmond, county of Richmond, State of New York, have invented certain new and useful Improvements in Processes of Utilizing Liquefied Gases, of which the following is a specification.

My invention relates to a process for utilizing liquefied gases and the like, and has for its object to produce a struct ure in which such gases, and especially liquefied air, can be employed to advantage.

My invention consists in a process for utilizing gases and the like, an example of which will be fully set forth and the characteristic features of the invention claimed.

In the drawing forming part hereof I have illustrated a form of apparatus for carrying out my invention. This apparatus is shown in sectional elevation and is in some degree diagrammatic and illustrative.

In the drawing, a is a suitable tank or reservoir, herein shown as open at the top and adapted to contain liquefied gases.

b is a stand-pipe which forms part of the liquidcirculating system hereinafter mentioned. The liquefied-gas reservoir communicates with the stand-pipe by pipe 0, provided with a suitable valve or valves 61 and preferably with an injection-nozzle e. The stand-pipe b may be provided with a domef and forms part of a circulatory system which is likewise comprised in part by a pipe g, preferably provided with a suitable valve h. The pipe 9 communicates with the interior of the stand-pipe 1), near the top thereof, passes through the furnace or heateril in a coil h, and thence extends to the lower part of the stand pipe I). A pipe j extends from the dome f of the stand-pipe b to carry off the gases for use. The liquefied gas is pumped from the reservoir a to the stand pipe I) through the pipe 0 by the pump is, whose cylinder Z is provided withamotive fluid through the pipe m, which communicates with the dome fof the stand-pipe b.

The operation of the device is as follows: Liquid air or other liquefied gas is placed in a reservoir a and a suitable liquid is placedin the liquid-circulating system, standing about up to the height shown in the stand-pipe. The liquefied gas is pumped from the reservoir a to the stand-pipe b, passing through the nozzle e, the said gas upon striking the heated liquid in b expanding rapidly, thereby cooling the said liquid in its ascent therethrough, the products of expansion.-to wit, the gasbubbling up through the liquid into the dome 6o fand passing out of the pipe j, part of they.

said gas being operative through the pipe m to work the pump. The rush of the expandin; gas up the stand-pipe g causes acirculation of liquid, the hot liquid pouring into the stand-pipe b and the cold liquid flowing into the coil h, where it is heated, there being thus supplied a constant circulation of heated liquid. By regulating the heat of the liquidcirculating system the temperature of the expanded gas may be regulated, and thus the gas may be used for refrigerating and other ARNOLD KREUSLER.
